Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed July 10,1908. Serial No. 442,987.

To all whom it my concemf Be it known that I, JoHx MILLER F LEM- in thecounty of Carleton,Province of Ontario, Canada, have invented certainnew and useful Improvements in Butter- Separators, of which the'following is a specification.

My invention relates to improvements in butter separators of the type inwhich the butter is Separated from the milk or cream through the mediumof a rapidly rotating dasher, and the objects of the invention are toprovide improved means for driving the dasher and for effecting a bettercirculation to increase the elfectiveness of the dasher. The form ofdasher commonly employed in this type of separator draws the airdownwardly from the top and distr'butes it to the sides or container ofthe milk and cream.

In the present invention, apertures are provided in the central part ofthe dasher of snificient. size to permit the milk orcream to bedrawncentrally into the dasher and carried along with the downgoingstream of air, thereby creating an additional draft for the air and morethoroughly commingling therewith. In order to further increase theefiiciency of the circulation a turbine member is create a current ofliquid towards the same.

The invention is describedmore fully in the accompanying specificationsand drawings, in which, v

Figure 1 is a vertical section through the butter separator. Fig. 2 is aperspective view of the dasher. Fig. 3 is a perspective Fig. 4 is athrough the turbine me detail of the coupling for is a sectional'detailof the transverse section the shaft. Fig. (3 driving pinionf In thedrawings, like letters of reference indicate corresponding parts in eachfigure. Referring to. the drawings, A represents the frame of suitableconstruction, including a base 10 adapted to support the tub B or othercontainer for the milk or cream, and a standard 11 having bearings 12and 13 at the top thereof, supporting a horizontal shaft 14. This shaft4 is connected .by a short piece of flexible shafting 15, with avertically-extending shaft 16, slidably journaled in the bearings 17,and connected by a releasable coupling 18 with the shaft 19,

of the tub provided below the dasher adapted to which extends in the tuband-has the lower end thereof'stepped in the bottom of the tub. Thecoupling 18 may be of any desired form, and the form illustratedincludes a collar 20 secured to the top of the lower shaft havingrecesses 21 and 22 therein, into which a pin 23 on the uppershaftextends. In accordance with the present invention,

a friction driving mechanism is provided for actuating the shaft 19 andthis includes a main driving wheel C, supported from a standards,preferably having a set of ball bearings 25 around the outer end adaptedto reduce the friction of the driving wheel against the collar 26 ontheend of the shaft.

The driving wheel C is formed on the periphery, engaged by a conoidalpinion 28 which rotates with the shaft 14 and is longitudinalgiadjustable'therein, this being accomplish by providing a key 29 -in theshaft or other suitable means.

The pinion is fiber or other materi l,w hich will give a good frictiongrip against. the flange. 27, and it is held in resilient contact withsaid flange by means of a compression spring 30, abutting the same andthe bearing 13. v

For convenience in turning the large wheel C a handle 31 may beprovided, and in order to steady the shaft 14 a balance wheel 32 ispreferably inserted between bearings12 and 13. i 7

-The bottom of the dasher is formed of two disks, 37 and 38, eachof'which are providedwith a plurality of depressed portions 39-, whichare located opposite the straight portions of the other disk, the edgesof the straight portions on the upper disk being formed with adownwardly inclined flange; 40 adapted to direct the out oing stream ofair downwardly. The tu ular portion permits the air to pass between thedisks through 'table apertures 41' formed therein.
